Waste Management’s compressed natural gas trucks cut greenhouse gas emissions by 25 percent and reduce particulate matter by 90 percent, Automotive Fleet reports.
The waste and recycling company earlier this month added six CNG trucks to its fleet in Chico, Calif. “We see an average annual reduction of 22 metric tons of greenhouse gases and 8,000 gallons of diesel with the CNG trucks,” district manager Ryan West tells the publication.
The company also uses route optimization software and its truck engines are programmed to shut down automatically after idling for five minutes to further cut emissions and fuel costs.
The company has used natural gas for heavy-duty trucks since the 1990s. Waste Management operates more than 2,200 alternatively fueled vehicles and says it has the largest fleet of natural gas collection trucks in North America.
Last year, Waste Management began building a facility to create pipeline-ready natural gas from its Milam Landfill in Fairmont City, Ill. At the time, the company said it expects it to begin delivering gas to the pipelines in late summer 2014.
